Preheat the oven to 375°F (190°C).
Chop the artichokes into small pieces and cut the cream cheese into smaller chunks.
In a mixing bowl, combine the cream cheese, sour cream, mozzarella cheese, garlic powder, onion powder, salt, chopped artichokes, and spinach. Mix until well combined.
Spread the mixture evenly into an oven-safe dish.
Bake for 20–25 minutes, or until the top is bubbly and golden.
Remove from the oven, let it cool slightly, and serve warm with your favorite dippers.
